Changes

* This was chosen by [[Asuca Hayashi]] as the fifth episode of ''[[Pocket Monsters Anime Premier 10]]''.

* Not counting the flashbacks, {{p|Pikachu}} and {{p|Meowth}} were the only two species of Pokémon seen in this episode. This is the lowest number of Pokémon species appearing in an anime episode.

* The episode's plot later became similar to that of ''[[SM091|A Plethora of Pikachu!]]'', which also revolves around a location where a large number of Pikachu live. In addition, that episode marked the anime's move from its Thursday 6:55 PM time-slot to a Sunday 6:00 PM slot, the first time the show changed its airing day since the aforementioned EP038 incident.

* The events of ''[[EP034|The Kangaskhan Kid]]'' were referenced in the beginning of this episode.

* In this episode, {{Ash}} crashes into a tree. In response, {{an|Misty}} says "Watch out for that tree", a catchphrase from the ''{{wp|George of the Jungle}}'' universe.
